Abstract
The present work is placed in the framework of the preparation for the interpretation
of the seismic space data from the space mission CoRoT. In this context, rotation have
become one of the most limiting factors when analysing the observed spectra of stars.
A general view on the effects of rotation on the oscillations
is given from the point of view of a linear perturbation analysis.
As well, the latest results about the effect of shellular rotation on adiabatic
oscillation frequencies are addressed. Finally,
the role of rotation on asteroseismic diagnostics is discussed.
In particular, échélle diagrams and analysis of rotation
profile variations are examined.
